Description

  The present invention relates to a packaging for packaging cosmetics, medicines, foods, etc. (packaging boxes) with plastic film, and more particularly to a tool for packaging rectangular hexahedral packaging boxes with rectangular plastic film pieces.

  Packaging of products by high-mix low-volume production, re-packaging of small quantities of products that have been damaged during transportation and management, etc. are unfamiliar with packaging machines that perform large-scale packaging in a short time. For this reason, in the past, the packaging process, which is a packaging process, wraps a packaging box with plastic film pieces and bonds them together (torso), and the plastic film pieces projecting from each end of the packaging box after the trunking. All the bending and pasting was done manually. However, this has the disadvantage of requiring time and effort.

  An object of the present invention is to provide a packaging tool that reduces the time and labor required for packaging a small amount of merchandise.

  The present invention relates to a tool for wrapping a rectangular hexahedron box with rectangular plastic film pieces, and a pair of guide members for linearly guiding the box arranged and connected to each other at intervals. And a supporting member for defining a supporting surface for supporting the box on one side between the two guiding members, and two opposed to each other and directed to one and the other with respect to the guiding direction by the guiding members. Two claw members, each of which has a support surface for supporting the box on one surface thereof and is movable in the guide direction, and the other claw member extends obliquely downward; A heating device that defines a heating surface between the two guide members, the guide surface defined by the one claw member, the guide surface defined by the support member, and the heating surface defined by the heating device are on these surfaces The box is the draft The plastic film pieces are sequentially arranged toward one of the guide directions so as to be slidable in the direction, and the support surfaces defined by the support members are relative to each other of the plastic film pieces that are placed on the box and hang down below one side of the box. Two first passages extending in the guide direction for a pair of end portions, and two second passages respectively connected to the first passages, and arranged at intervals with respect to the guide direction. Two second passages extending obliquely so as to cross each other toward one of the directions, and a third passage extending in the guiding direction connected to both the second passages, and each claw member includes: When the mutually opposing ends of the plastic film pieces that are wound around the box and hang down below one side of the box are pressed, the end portions are bent.

  The guide member may be configured such that the other guide member is movable with respect to one guide member so that the interval defined by the guide members is variable.

  The support member includes two first plate bodies and two second plate bodies that are attached to both guide members and extend in the guide direction, and each first plate body and each guide member are interposed between them. The first plate and the second plate each define the second passage, and both the second plates define the third passage. It can be specified.

  The support member may further include a plate body adjacent to the heating surface. Further, the other claw member may be integrated with the support member. The plastic film piece may include a tear tape bonded thereto.

  According to the present invention, in order to wrap a box with rectangular plastic film pieces, the box covered with the plastic film pieces is placed on the support surface defined by the support member with the one side down, and the support surface is placed on the support surface. It is slid toward the heating surface, that is, toward one of the guide directions by both guide members. During the sliding, both ends of the plastic film piece hanging below one surface of the box reach the third passage through the first passage and the second passage sequentially. The second passages extend obliquely so as to be spaced apart from each other with respect to the guide direction and intersect each other toward one of the guide directions, so that both ends of the plastic film piece have both the second passages. As they pass, they are sequentially folded toward one another. Then, when reaching the third passage, the folded ends are respectively placed on the support surface, are folded under one surface of the box so as to face each other, and partially overlap each other. Both ends of the plastic film pieces bent so as to overlap each other reach the heating surface by the subsequent sliding operation, and these overlapping portions are thermally melted and joined to each other on the heating surface. As a result, so-called trunking is completed, and the plastic film piece is wound around the box to form a rectangular tube shape.

  Next, one end of the plastic film piece having a rectangular tube shape and having both ends protruding from the box is placed between the guide members, and the plastic film piece is moved toward one claw member. Press against the claw member. As a result, one of the pair of side surfaces opposed to each other at the end of the plastic film piece is bent toward one surface of the box and rests on the support surface defined by the one claw member. . Accordingly, one of the one side surfaces is bent so as to face one surface (lower surface) of the box.

  Next, the one claw member is moved toward the other claw member. At this time, since the other claw member is directed obliquely downward, a part of the one claw member rides on the other claw member. As a result, the other of the pair of side surfaces of the plastic film piece hits the other claw member and is bent so as to face one surface (lower surface) of the box.

  Next, the box is moved from the support surface of the one claw member onto the support surface of the support member, and the box is slid toward the heating surface. As a result, the remaining pair of side surfaces of the plastic film piece passes through the first passage, the second passage, and the third passage, and both side surfaces are sequentially bent toward each other during this time. , And partially overlaps the pair of side surfaces bent in advance. The pair of side surfaces that partially overlap are thermally welded by the subsequent sliding operation of the box onto the heating surface. These operations are similarly performed on the other end of the plastic film piece. Thereby, so-called ear folding is completed, and packaging of the box is completed at the same time.

  According to the present invention, in the packaging of the box by the plastic film piece and the ear fold, the box with the plastic film piece between the guide members can be moved or slid in a short time and easily. It can be carried out.

  By making one of the two guide members movable with respect to the other and making the mutual distance between the two guide members variable, packaging of various sizes of boxes can be made possible.

  In addition, when the support member is a plate attached to each of the guide members, when one of the guide members is moved to change the width dimension of the both guide members, the size of the support surface defined by the support member is large. It can be changed according to the size of the box to be applied.

  When the support member includes a plate adjacent to the heating surface, the pressing member exerts a pressing force on the folded portion of the plastic film piece that has passed through the third passage on the plate, to the heating surface. Prior to movement, the folded surface can be made flatter.

  Referring to FIGS. 1 and 2, a packaging tool according to the present invention is indicated generally by the numeral 10.

  The packaging tool 10 is used for packaging a rectangular hexahedral (cuboid or cubic) box 12 with a rectangular plastic film piece 14 (see FIG. 3). An example of the box 12 is a cosmetic box in which cosmetics, medicines, foods, and the like are placed. The plastic film piece 14 is made of a thermoplastic resin such as polyethylene, polypropylene, or polyvinyl alcohol.

  The packaging of the box 12 by the packaging tool 10 is performed through so-called trunking and ear folding, as in the case of conventional manual packaging. The trunking is performed by winding the plastic film piece 14 around the box 12 around the box 12 so that both ends thereof partially overlap each other, and heat-welding the both ends. The plastic film piece 14 is usually wound around the four sides between the top cover and the bottom cover of the box 12. At this time, the plastic film piece 14 after the waisting has a rectangular tube shape, and both end portions in the axial direction of the rectangular tube protrude from both lids of the box 12 respectively. Next, the ear folding is performed. The edge fold is made by bending each end projecting in the axial direction of the rectangular tube toward each lid of the box 12 and thermally welding one part of the both end portions that partially overlap each other. Done. The plastic film piece 14 is selected and prepared in advance so as to have a size that enables the waist and the ear folding. In the illustrated example, the plastic film piece 14 has a so-called tier tape 15 for later tearing it and unpacking the box 12.

  The packaging tool 10 includes a pair of guide members 16 and 18 for the box 12, a support member 20 for supporting the box 12, two claw members 22 and 24 for making the ear fold, and the thermal welding. And a heating device 26 for generating the above.

  Both guide members 16 and 18 are spaced apart from each other and connected to each other, and receive the box 12 between them, and serve to guide it linearly with respect to the box.

  Both guide members 16 and 18 shown in the figure are formed of relatively elongated plate members, and are placed on a pair of spacers 28 extending in the transverse direction of the both guide members 16 and 18 at both ends thereof. It is fixed to the spacer 28. On the other hand, the other guide member 18 is movable relative to the one guide member 16 so that the mutual distance between the other guide member 18 and the one guide member 16 can be adjusted. Thereby, the box 12 of various magnitude | sizes can be made into a packaging object by changing the space | interval between both the guide members 16 and 18. FIG.

  In the illustrated example, a rail 30 extending in a direction crossing both guide members 16, 18 is attached on each spacer 28 in order to make the guide member 18 movable and to interconnect the both guide members 16, 18. A slider 32 that can slide along the rail 30 is attached to the lower surface of the other guide member 18. Further, a screw member (not shown) for pressing the guide member 18 against the rail 30 and releasably fixing it to the spacer 28 is screwed into the guide member 18. A knob 34 is attached to the top for rotating the screw member.

  Instead of the illustrated example, the other guide member 18 is fixed to both spacers 28 in the same manner as the one guide member 16, and both guide members 16, 18 are connected to each other via both spacers 18. Can be. According to this, the mutual interval between the guide members 16 and 18 is set to only one size that can correspond to one size box.

  The spacers 28 attached to both guide members 16 and 18 have a required height or space required for the packaging operation between the work table and both guide members 16 and 18 when the packaging tool 10 is placed on the work table. Is provided to ensure.

  The support member 20 defines a support surface for supporting the box 12 on one surface (lower surface) between the guide members 16 and 18. The box 12 can be moved along the guide member, that is, in the guide direction under the guide action of the guide members 16 and 18 by holding the box 12 with the finger F and sliding it on the support surface. At this time, the box 12 comes into contact with both guide members 16 and 18 on both side surfaces opposed to each other, thereby receiving the guide action by the guide members 16 and 18.

  In the illustrated example, the support member 20 includes two first plate bodies 34 and two second plate bodies 36 that are both elongated in the guide direction, and these plate bodies are disposed between the guide members 16 and 18. A support surface for the box 12 is defined.

  Both the first plate bodies 34 and the two second plate bodies 36 are located at substantially the center in the longitudinal direction of the guide members 16, 18, and the upper surfaces of these plate bodies 34, 36 and the both guide members 16, 18. Are located on the same plane.

  Both the first plate bodies 34 and the second plate bodies 36 are respectively attached to the guide members 16 and 18. More specifically, the first plate bodies 34 are respectively attached to the lower surfaces of the guide members 16 and 18 via brackets 38, and the first plate body 34 is interposed between the first plate bodies 34 and the guide members 16 and 18. There is a gap 40 extending in the guide direction. Further, both the second plate bodies 36 are directly fixed to the lower surfaces of the both guide members 16 and 18 and project between the both guide members 16 and 18. Therefore, when the mutual interval between the guide members 16 and 18 is widened or narrowed, one of the first plate bodies 34 and one of the second plate bodies 36 together with the movable guide member 18 are guided by the guide member 18. Accordingly, the support surface corresponding to the size, that is, the thickness dimension of the box 12 disposed between the guide members 16 and 18 is defined.

  There is a gap 42 defined between the first plate 34 and the second plate 36. Both the gaps 42 are arranged at an interval with respect to the guiding direction. Further, both the gaps 42 extend obliquely so as to cross each other toward one of the guide directions (leftward in FIG. 2), and more specifically, in the extension of these gaps 42. . Further, there is a gap 44 defined between the first plate bodies 34 and between the second plate bodies 36.

  The gap 40 between the plate 24 and the guide members 16 and 18, the gap 42, and the gap 44 defined by both the second plates 36 are respectively plastic film pieces during packaging operation by the packaging tool 10. The first passage, the second passage, and the third passage permitting a part of the passage 14 are formed. The first passage 40 is connected to the second passage 42, and the second passage 42 is connected to the third passage 44.

  As will be described later, the first passage 40 passes through both ends of the plastic film piece 14 covered on the box 12 that is slid on the support surface toward the one of the guide directions for the trunk ( 3) and also passes one of the two pairs of ends 66 of the plastic film piece 14 previously wound around the box 12 by the waist for the ear folding (FIG. 10). The second passage 42 has a role of passing the end portions 62 and 66 of the plastic film piece 14 to be folded for each of the waistline and the ear fold (FIGS. 4 and 11). Moreover, the 3rd channel | path 44 has a role which lets the edge parts 62 and 66 of the plastic film piece 14 just after bending pass (FIG. 5).

  Preferably, as in the example shown in the figure, a pair of third plates are adjacent to the heating device 26 on the one side in the guide direction and at a slight distance from both the second plates 36. 46 is arranged and fixed to the lower surfaces of both guide members 16,18. There is also a gap between the third plate bodies 46. Both third plate bodies 46 project between the guide members 16 and 18 respectively, and define a part of the support surface for the box 12. Each plate 46 has a protrusion 47 extending toward the other side of the guide direction (rightward in FIG. 2) and inclined downward from the second plate 36. Instead of this example, each third plate 46 and each second plate 36 may be integrated.

  In the case of an example in which one guide member 18 is fixed and the distance between both guide members 16 and 18 is not changed, both first plate bodies 34 can be replaced with a single plate body. Also, both the second plate bodies 36 can be replaced with a single plate body. However, a single plate that replaces both the second plates 36 is provided with a notch that defines a third passage 44 connected to the second passage 42. Both the third plate bodies 46 can be replaced with a single plate body.

  The plate members 34, 36, 46 are replaced with the guide members 16, 18, instead of the illustrated example. For example, the substrates (see FIG. (Not shown) can be supported between the guide members 16 and 18 via an appropriate support (not shown).

  Both the claw members 22 and 24 are disposed between the two guide members 16 and 18 adjacent to the other side of the first plate 34 of the support member 20 with respect to the guide direction, and one and the other side with respect to the guide direction. And are opposed to each other in the guiding direction.

  Both the claw members 22 and 24 are each composed of a pair of tapered plate bodies 48 and 50 disposed between the both guide members 16 and 18 at intervals.

  One claw member 22 is suspended by both guide members 16 and 18 via a pair of brackets 52 fixed to these plate bodies 48 respectively. Both plate bodies 48 also define a support surface for supporting the box 12 on one surface (lower surface) which is on the same plane as the support surface defined by the support member 20.

  Both brackets 52 are connected to a pair of rails 54 provided on the top surfaces of both guide members 16 and 18 and extending in the longitudinal direction of both guide members 16 and 18 so as to be movable along the rails, that is, in the guide direction. It is fixed to a block-like slider 56.

  Both brackets 52 are also connected to each other by a bar member 58 attached to them and extending in the transverse direction of both guide members 16, 18. Thereby, both plate bodies 48 can be moved simultaneously in the guide direction.

  On the other hand, the two plate bodies 50 of the other claw member 24 are formed integrally with the pair of plate bodies 34 of the support member, and are inclined downward. For this reason, when one claw member 22 is moved in one of the guide directions, the tip of one claw member 22 can ride on the tip of another claw member 24.

  In the case of the above example in which the distance between the guide members 16 and 18 is unchanged, the guide members 16 and 18 can be made of a single plate. Moreover, about the both plate bodies 50 of the other nail | claw member 24, it can comprise as an independent thing isolate | separated from the both plate bodies 34 of the support member. In this case, both plate bodies 50 can be fixed to the bottom surfaces of both guide members 16 and 18 like the second plate body 36.

  The heating device 26 disposed adjacent to the support member 20 on the side opposite to the claw member 24, that is, one side in the guide direction of the support member 20 is an electric heating plate in the illustrated example. , 18 define a flat heating surface. The heating surface is on substantially the same surface as the support surface.

  The packaging of the box 12 with the plastic film piece 14 using the packaging tool 10 can be performed as follows.

  First, the box 12 covered with the plastic film piece 14 is held in the hand F, and this is placed on both plate bodies 34 of the support member between the both guide members 16 and 18 (FIG. 3). In general, a plastic film piece 14 is placed on the box 12 so as to cover the periphery of three of the four sides between the top lid and the bottom lid of the box 12.

  At this time, a part 62 of the plastic film piece 14 hangs down from the remaining one side surface (lower surface) of the box 12 in the vertical direction (downward), protrudes laterally from the upper lid and the bottom lid, and hangs down downward. The part 62 extends downward through the first passage 40. Both spacers 28 ensure an interval between the two end portions 62 of the plastic film piece 14 to hang down between the work table on which the packaging tool 10 is placed. At this time, the box 12 is in contact with the guide members 16 and 18 via the plastic film pieces 14 on both side surfaces facing each other.

  Next, the box 12 is moved toward one side in the guide direction, and is sequentially slid on the both plate bodies 34 and both plate bodies 36 of the support member. Thereby, the both ends 62 of the plastic film piece 14 are guided and moved from the first passage 40 to the second passage 42 (FIGS. 4 and 5). Both end portions 62 of the plastic film piece are bent toward the bottom surface of the box 12 while moving in the second passage 42, and then the both end portions 62 ride on the second plate 36, and the third plate It partially overlaps in the passage 44. As a result, the two end portions 62 are bent until they are opposed to the bottom surface of the box 12, that is, approximately 90 degrees.

  Since both the second passages 42 are spaced from each other in the guiding direction, the bending of the both end portions 62 of the plastic film piece occurs before and after in time. For this reason, after one of the both end portions 62 is bent, the other end portion 62 is bent so as to overlap the one end portion.

  When the box 12 is further moved, both ends 62 of the plastic film pieces that are bent and overlap each other on the lower surface of the box 12 slide on both the plate members 36 and 46 of the support member (FIG. 6), and then the heating device 26 defines. It reaches the heating surface and slides over the heating surface (FIG. 7). At this time, the superposed portions of the both end portions 62 are thermally melted and bonded to each other (thermal welding). At the same time, the overlapping portions of both ends of the tear tape 15 are also heat-welded. As a result, the waistline is completed (FIG. 8).

  Next, the box 12 around which the plastic film piece 14 is wound by the waist is rotated 90 degrees from the state shown in FIG. 8, and the box 12 is placed on the both plate bodies 48 of the one claw member 22. The box 12 is placed by moving the claw member 22 to the other side in the guide direction in advance to secure an insertion space for the box 12 between the guide members 16 and 18. This is done by inserting a box between 18 and then moving it toward the claw member 22. At this time, one of the pair of parts 64 of the two pairs 64 and 66 facing each other at the other end of the rectangular tube projecting from the top cover or bottom cover of the box 12 hits the tip of the claw member 22 and is bent. 12 is pressed against one surface (the lower surface defined by the upper lid or the bottom lid) (FIG. 9).

  Thereafter, with the box 12 placed on the claw member 22, the claw member 22 is moved toward one side in the guiding direction until it rides on the other claw member 24. At this time, the remaining part 64 of the plastic film piece hits the other claw member 22 and is bent and pressed against the one surface of the box 12.

  Subsequently, the box 12 is moved toward one side in the guide direction. At this time, since a part of the one claw member 22 rides on the other claw member 24, the movement from the one claw member 22 to the first plate bodies 34 of the support member is performed smoothly.

  When the box 12 slides on the first plate 34 of the support member, the other pair of end portions 66 of the plastic film piece 14 remaining unfolded pass through the first passages 40 respectively ( FIG. 10). Further, when passing over the second plate 36, both portions 66 pass through the second passages 42, are bent in the same manner as in the above-mentioned waistline, and partially overlap each other (FIG. 11). .

  When the box 12 continues to move, both portions 66 bent to the lower surface of the box 12 slide on the third plate 46 and further slide on the heating surface, and an overlapping portion of both portions 66 is interposed therebetween. It is melted by heat and bonded to each other (FIG. 12). As a result, the edge folding at one end portion of the rectangular tubular plastic film piece 14 is completed.

  Thereafter, similarly, the other rectangular tube-shaped end portion of the rectangular tube-shaped plastic film piece 14 is also subjected to ear folding. Thereby, the packaging of the box 12 by the plastic film piece 14 is completed.

  As shown in FIG. 13, a U-shaped cross-section for pressing the plastic film piece 14 against the three side surfaces of the box 12 in order to maintain a good covering state of the plastic film piece 14 on the box 12 in the above-described trunking operation.
